 		 #166690 - Not necessarily true
Responding to: Christoph Franck's previous message
Christoph Franck said:
C simply doesn't know about any of these operations, so the compiler never uses the instructions.

Although 'C' itself doesn't know about them, the compiler might still decide that it can use them to advantage. It may also include Libraries that use them - so your compiler output may still include these instructions!
